A good tenet is unambiguous in application and interpretation. There's no way to misuse a good tenet. Some of Amazon's are incredibly easy to abuse: frugality, disagree and commit, be right a lot. Here are some strong ones that may or may not be useful to your company:
If a decision is easy to reverse, don't spend to much time figuring out of it's the right decision.
Prioritize paying for something over building something assuming the annualized cost of an engineer is ~$X (e.g. $1MM).
Document and test internal systems as if you were selling them to a customer.
Simple, repetitive and dumb over complex, convenient and smart.
Plan to throw the first iteration away.
Be honest, and be honest to customers.
Always assume disaster can and will strike at the worst possible time. Better safe than sorry.
Prioritize people over processes. This means don't follow some dumb process if it makes everyone upset. Change the process.
Admit when you were wrong.
I’ve generally thought of tenets as smaller in scope; “on this team/project, our tenets are _____” They would keep overall company vision in mind, but would break it down more specifically to the local situation, helping to guide people to a common understanding of “we have a generally frugal culture/LP, but in this case, we will value speed over cost in this type of trade off”.
They are indeed LPs but they were effectively framed as tenets everywhere possible. I'd be wary of this sort of Amazon culture creeping into other orgs.
Not this one. This one has no plausible opposite. It's just going to lead to weasel-y debates. You can't remind someone else to admit that they're wrong, because they don't think they're wrong.
Note that the leadership principles are also a form of tenets, with their own internal contradictions that is waved away by a usual "it's a constructive tension".
Are tenet and non-functional requirement about the same thing?
Oh wait I think they stopped doing that after they "lowered the bar" for being a principal engineer there so much that most of them can no longer code. And that's how there was a sudden explosion of senior principal engineers...
The article is a good first introduction to the framework, although I have to admit that I found the tenets mentioned in the article not very convincing.
Thinking about how you would finish the sentences "We would never do..." and "We would always do..." is a good way to start drafting tenets.
A good quality check for a tenet is to ask if the tenet could be used for decision making, for example in a heated team discussion.
